Objective: To present a large series of oral haemangiomas in children, analyzing the clinical characteristics, treatment and outcome of oral haemangiomas in 28 children. Material and Methods: We conducted an observational retrospective study, reviewing medical records with clinical diagnosis of haemangioma between 1990 and 2006 at the Children's Maxillofacial Surgery Service of the Hospital Universitario la Fe, Valencia. All patients with a clinical, radiographic, pathologically confirmed diagnosis of oral haemangioma were included. Results: The study included 28 patients (19 females and 9 males) with a mean age of 4.27 years (range 0-14 years). Nine were congenital haemangioma. The most frequent location of oral haemangioma was in the lip with 23 cases, followed by three cases in the tongue and 2 in the buccal mucosa. The mean diameter of the lesion was 1.67 cm (range 1-3cm). The mean duration of the lesion was 6.3 months (range 1 month to 5 years). Of the 28 haemangiomas, 13 were surgically removed, 2 were treated with embolization and 13 disappeared spontaneously. The mean follow up was 2.7 months (1-8 months). There were no cases of recurrence. Conclusions: Haemangiomas usually present in children, and can be seen from birth. They have a predilection for females. They are uncommon in the oral cavity. In the oral region, the most common location is the lip. Most congenital haemangioma regress spontaneously without treatment. The treatment of choice is surgical excision of the lesion.

Objective: The aim was to analyze the clinical characteristics, treatment and outcome of 8 orofacial dermoid cysts (DC) in pediatric patients. Material and Methods: A retrospective observational study was made, reviewing the medical records with clinical diagnosis of dermoid cyst between 1987 and 2006 in the Children's Maxillofacial Surgery Department of the Hospital Universitario La Fe, Valencia, Spain. The following data were collected: sex, age, location, size and duration of the lesion, treatment, length of follow-up, and recurrence. Results: Eight patients (3 girls and 5 boys) with a mean age of 2.7 years (range 0-12 years). Four DC were located in the oral area (3 sublingual and 1 lingual), one in the periorbital and three in the nasal areas. The size ranged from 0.8 cm to 4 cm. The mean duration of the lesion was 13.7 months (range 4 days to 2 years). All DC were diagnosed pathologically following surgical removal of the lesion. There were no recurrences. Conclusion: The appearance of DC in the maxillofacial region of pediatric patients is uncommon. The floor of the mouth is the most frequently affected area in the oral cavity. Treatment is surgical removal of the lesion. Recurrence is unusual.

Objective: To present 57 cases of oral ranula in children, analyzing the clinical characteristics, treatment and outcome of these lesions. Methods: The clinical histories of patients diagnosed with oral ranula, seen between 1998 and 2008 at the Oral and Maxillofacial Surgery Unit of a reference Children's Hospital (0-14 years) were reviewed. All patients with clinical diagnosis of oral ranula were included. Results: Fifty-seven patients, 21 boys and 36 girls, with a mean age of 5.1 years were included in the study. Thirtytwo cases were located on the left side of the floor of the mouth. The lesion diameter varied between 1 and 3 cm in 27 cases, 22 were less than 1 cm, and 8 were larger than 3 cm. Fifty-four cases were asymptomatic and 3 ranulas had pain on swallowing. Twenty-two cases were resolved by opening with a tract dilator and 35 by marsupialization. Seven cases recurred at a mean of 12 months after treatment, three of these from the marsupialization group. Conclusion: The majority of the oral ranulas occurred in females, asymptomatic, on the left side of the floor of the mouth, with a mean size of 1 to 3 cm; all lesions were treated by surgery, of which 7 recurred.
